My dad doesnt understand and thinks its a phase

Tell whoever this;

"You will never be able to fully understand how I feel non-binary as you do not feel this way, just as I can never be able to fully understand how you feel [insert gender] as I don't feel that way. However, we can ask each other how we feel and understand it in terms of how the other person feels, even if not for our self. We can accept eachother, just as males and females accept they feel different about gender identity." [pause for breath] "It's like when you are a rugby fan and you can't understand why people like football, so you go to some football games and you can understand why people like football as you have been in their in-group. With gender, and anything else biological, it isn't like that. You can never go to those football games - so you'll just have to ask football fans why they like it."

You can change the analogy if you want to tailor it to what the person you're speaking to likes/dislikes.

I've found this quite effective for anything when getting people to understand, use their language but use it to your advantage. That way - you're taking what they think of it being a "phase" but getting what you want [hopefully] of the name and/or pronouns. Ending to make sure it has benefits for them, and also for you, and making them know it might not be a phase and they'll have to accept that. Maybe it's not ideal, but sometimes you can't change people's minds and you have to find another way.

 

My dad thinks the same thing....

I feel you!

 

It might of been a bad idea to come out around Christmas as he is busy and could blame you for ruining Christmas
